The strength question is easy and most people waste it. The weakness question is hard and most people dodge it, which the interviewer notices, because the dodge is the thing they were testing for. The answer to both is the same shape: one real thing, one piece of evidence, under a minute. A strength with a number. A weakness with what you do about it and a sign that it is working. "I am a perfectionist" fails on both counts and every interviewer has heard it a hundred times.
Key points
- One strength, chosen from the posting's must-haves, with a story and a number.
- One real weakness, not a strength in disguise, with what you do about it.
- The weakness must not be a must-have of the role. Pick one that does not disqualify you.
- Under a minute each. The weakness answer is shorter than the strength answer.
- The dodge is what they test for. Name a real one.
The strength
Pick it from the posting. The must-haves list has three or four skills, and one of them is the one you are best at. That is the strength, because it is the one they are hiring for. Then the evidence: one story, one number. "My strength is getting a stalled project moving. At my last company the migration had been stuck for six months. I took it over in March, broke it into two-week pieces, and we shipped in September." Forty seconds.
A strength with no evidence is an adjective. "I am a strong communicator" is an adjective. "I wrote the onboarding doc that cut the new-hire ramp from six weeks to three" is a strength.
The weakness
Three rules. Real, so it costs something to say. Not a must-have, so it does not disqualify you. Worked on, so the answer ends with what you do and a sign it helps.
"I over-prepare for meetings and spend time I do not have. I now timebox prep to thirty minutes and keep a template, and in the last review my manager said the meetings were sharper and I was less stretched." Thirty seconds. Real, not fatal for most roles, and the second half is the answer.
A weakness answer is a story about improvement. The weakness is the first sentence.
The answers that fail
| Answer | Why it fails |
|---|---|
| "I am a perfectionist" | A strength in a costume. Everyone has heard it. |
| "I work too hard" | The same |
| "I cannot think of one" | The dodge, which is the thing being tested |
| A must-have of the role | Disqualifying. "I am not great with deadlines" for a project role. |
| A character flaw with no remedy | "I am bad at people" with nothing after it |
| A list of three | One is the answer. Three is a confession. |
Six strengths that pass
Each with the evidence it needs:
- Getting unstuck work moving. A stalled project, what you did, the ship date.
- Writing things down. A doc, who used it, what it changed.
- Finding the root cause. A bug or a problem that recurred, what you found, that it stopped.
- Saying no to scope. A project that shipped because you cut something, with the date.
- Teaching. People you trained, how fast they got productive.
- Numbers. A decision you changed with data, and the result.
Six weaknesses that pass
Each with its remedy:
- Over-preparing. Timeboxing, and the review that noticed.
- Slow to delegate. A rule you set, a thing you handed off, how it went.
- Hard to interrupt mid-task. Blocked focus time plus a visible status, and fewer surprises.
- Public speaking. A course or a group, and the last talk you gave.
- Too direct in writing. A reread rule before sending, and the feedback since.
- Avoiding a tool or a skill the role does not need. A course in progress, with a date.
When they ask for three
"Three strengths" is still answered with one that has a story, then two named in a sentence each. "Three weaknesses" is answered with one real one worked on, then "and I have been asked to speak up earlier in meetings, which I am working on" and stop. The third is a dodge nobody expects you to fill.
Practice, on this site
Practice asks both, grades the strength for evidence and the weakness for a real admission and a remedy, and tells you when the answer was an adjective or a dodge. The guide on mock interviews has how to run it.
Questions
Is it a trick question?
No. The strength is a check that you know what the role needs. The weakness is a check that you are honest and that you improve. Both are answered by a story.
Can the weakness be something I fixed?
If it is fixed, it is not a weakness. "I used to miss deadlines, and now I never do" is a dodge. Pick one that is better and not gone.
What if my weakness is the job?
Then the job is wrong, or the weakness is. A weak writer applying for a writing role needs a different answer, and the answer is to apply for a different role.
How honest is too honest?
A weakness that would make a reasonable manager not hire you is too honest for the room. The rule about must-haves is the line.
Does the strength have to be from work?
It has to have evidence. A number from a volunteer role or a project counts. An adjective from anywhere does not.
